The Killer's Game Openh264 -

is an open-source video codec (encoder/decoder) released by Cisco Systems.

// Assuming game gives you RGB24 void RGB24toYUV420(uint8_t* rgb, uint8_t* yuv, int width, int height) // Standard conversion matrix (BT.601) for (int i = 0; i < width * height; i++) int r = rgb[3*i]; int g = rgb[3*i+1]; int b = rgb[3*i+2]; yuv[i] = (66*r + 129*g + 25*b + 128)>>8 + 16; // Y the killer's game openh264

| Problem | Solution | |---------|----------| | High CPU usage | Reduce resolution or use iRCMode = RC_QUALITY_MODE | | Color shift | Ensure correct RGB↔YUV matrix (BT.709 for HDTV) | | Dropped frames | Increase iMaxNalSz and use EncodeParameterSets() before first frame | | Audio sync | Store PTS (presentation timestamps) separately — H.264 stream has no audio | is an open-source video codec (encoder/decoder) released by
